Living With Nature Monthly Program

Tucson Audubon Society’s Living with Nature program is an opportunity to meet, to make friends with other Audubon members here in our community, to share our photography and wild birding tales, to find out about Tucson Audubon events and field trips, and to build our knowledge and the human connection to nature and natural habitats. The Living with Nature talks presented are varied, shared in a weekly email to the membership and here on the Tucson Audubon website. Living with Nature is open to the public and there is no charge to attend. We are truly grateful to our speakers who donate their time and talent in contributing to this effort. If you have ideas for a future presentation, scroll to the bottom of the page for a form to complete, or email events@tucsonaudubon.org.

Gray Hawks on the San Pedro with Ariana La Porte

Desert riparian ecosystems are among the most threatened biodiversity hotspots in the United States, and efforts to conserve them have been increasing. Ariana La Porte and her team at the University of Arizona assessed the 20-year impact of establishing a National Riparian Conservation Area along the San Pedro River (SPRNCA) in Arizona, which removed grazing and agriculture from the riparian corridor. They examined changes in the population, productivity, habitat, and diet of a top predator, the gray hawk (Buteo plagiatus), to determine how the cessation of anthropogenic use affected the ecosystem. The gray hawk population on the SPRNCA has nearly doubled since the conservation area was established, and pairs now nest in a wider variety of vegetation types and eat a more diverse assemblage of prey. They propose that the elimination of grazing and agriculture in the SPRNCA created habitat for gray hawks in areas that were previously unsuitable by allowing grasslands to regenerate and become habitat for their prey. The success of conservation measures in the SPRNCA serves as a model for the potential of similar management strategies to improve the health of other riparian ecosystems in the arid regions of the United States.
